Yeah, I thought this point in the article was off target:

> Trillions of dollars were spent on wind and solar projects over the last 20 years, yet the world’s dependence on fossil fuels declined only 3 percentage points, from 87% to 84%.

Isn't this because we are at the beginning of an exponential curve? Or at least a sigmoid curve. That money wasn't wasted. A growth curve will look like nothing much until suddenly one day it takes over.
